Geometric Origami

A book about the geometry of origami, with folding instructions for fifteen regular polygon models.

Geometric Origami

How do you fold regular polygons?

Can more be achieved by folding paper than by traditional ‘ruler and compass’ constructions?

Geometric Origami reveals some of the rich mathematics inherent in paper folding, and will help origamists, mathematicians and the interested general reader appreciate the value of studying the geometrical properties of folding a square of paper.

Part I of the book covers the mathematical theory of origami constructions.

Part II includes step-by-step folding instructions for fifteen regular polygons, from the equilateral triangle to the 19-gon.

Written by the mathematician and origamist Robert Geretschläger, Geometric Origami will appeal to:

The author

His interest in origami goes back to childhood — fond memories of struggling to fold a frog without its legs turning to mush are still very present. A number of his published mathematical papers are somehow related to origami.
